    Clawback of heating services in Beacon research homes (PDF 523KB)

    Andrew Pollard, Nikki Buckett

    Increased energy efficiency of hot water and space heating should reduce the cost of providing these services. However, the phenomenon of 'clawback' - where occupants use the improved heating system to increase comfort, can alter the effect of energy efficiency upgrades. In this work, the data from the Papakowhai Renovation Project, and the Waitakere NOW Home® are used to assess the clawback from the water heating and space heating services in ten New Zealand homes.

    The Environmental Impact of the Waitakere NOW Home®: A Life Cycle Assessment Case Study (PDF 2MB)

    Nick Collins, Andrea Blackmore

     

    A Life Cycle Assessment case study of Beacon Pathway's Waitakere NOW Home® indicates that the greatest environmental impact of a house is not during construction or manufacturing, but from its operation over the life of the house.  The study focused on the house itself over a 100-year period in New Zealand, with a family of four inhabiting it. Heating, lighting and hot water were considered, and seven key building systems were evaluated separately.  Life cycle phases of construction, use, maintenance, transportation of materials to site and end of life were included.  New Zealand-specific Life Cycle Inventory data was used, wherever possible, for building materials.  However, where New Zealand data was unavailable, European industry data was used.

    Solar Water Heating in the Waitakere and Rotorua NOW Homes and in three Papakowhai Renovation homes (PDF 1.3MB)

    Andrew Pollard

    This report describes and examines the performance of the solar water heating systems used in the Waitakere NOW Home®, the Rotorua NOW Home® and three of the Papakowhai Renovation houses. A variety of systems were used in these houses and performance varied from 75% of the water heating being provided by solar in one of the Papakowhai  Renovation houses to 36% of the water heating needs being met by solar in the Rotorua NOW Home®.  Reasons for the performance levels are suggested.

    Waitakere NOW Home® Performance Monitoring: Six Month Report (PDF 176KB)

    Roman Jaques, Andrew Pollard

    Report of preliminary data from the first six months of monitoring while tenanted, and also the views of the occupants via the first of four post-occupancy evaluations.  This early analysis relied on disrupted data and was not considered very accurate.  Later reports NO102/3 and NO102/4 gave a more accurate picture of how the home performed.

    NOW Home Protocols: A toolkit documenting the Beacon approach to sustainable design (PDF 640KB)

    Karen Bayne, Roman Jaques, Annika Lane, Katja Lietz, Robin Allison

    Based on the experience of the early design process for the Waitakere NOW Home, this report recorded the basis for design decisions and product selection with the intention of becoming an internal resource document.  However, experience and monitoring of the house later changed Beacon's focus to concentrate on energy, water, IEQ, waste and materials.
